No issues here I know that on the web site that I was checking out they have revised the DR Browns and the tube things can be replaced with the BPA FREE ones
silversky32 since you already have those maybe you could check it out
\I think they look like they would be a real pain to clean ?? Not sure as I have not used them myself
And you were right about some of the Avent bottles you just have to check the boxes as they are labeled
